Star Wars actors teased an epic sendoff, the cast of Frozen sang, and action movie star Dwayne Johnson rolled out in a river boat as Walt Disney Co promoted its upcoming film slate to devoted fans. New footage from Star Wars: The Rise of Skywalker showed heroine Rey (Daisy Ridley) wielding a red, two-sided lightsaber, generating thunderous applause from roughly 6,000 people in the Anaheim Convention Center for the company's D23 Expo fan event. The movie is the ninth installment in the space saga started 40 years ago by George Lucas. It debuts in theatres in December. "It's kind of hard for me to understand the story is ending, but what an ending!" Anthony Daniels, who plays C-3PO, said onstage surrounded by cast members and droids R2-D2 and BB-8. Disney is dominating movie box offices this year, generating more than $US8 billion ($A12 billion) in ticket sales from Avengers: Endgame, The Lion King and other mega-hits. Saturday's presentation looked to the future and featured a parade of Hollywood's biggest stars. Dwayne Johnson made his entrance on a makeshift boat to promote Jungle Cruise, an action-adventure movie based on the Disney theme park ride. Johnson explained that the film was modelled after some of his favourite films such as the Indiana Jones series and Romancing the Stone. Like those movies, Jungle Book tells the story "heroic men kicking ass and saving the girl," Johnson dead-panned, prompting co-star Emily Blunt to come out in protest and introduce clips of her character jumping out a window and needing no assistance. In addition, Disney revealed scenes from Marvel movie Black Widow and a live-action re-telling of Mulan, brought Angelina Jolie on stage to talk about Maleficent: Mistress of Evil, and announced Game of Thrones star Kit Harington was joining the cast of superhero flick The Eternals, which also stars Jolie. Executives at Pixar explained the plot of upcoming film Soul. The movie tells the story of a middle-school music teacher who dreams of being a jazz musician and explores big questions such as "Why am I here?," they said. Idina Menzel and Kristen Bell sang alongside Frozen co-stars Josh Gad and Jonathan Groff, who crooned into a stuffed reindeer. Chris Buck, co-director of Frozen, said the November sequel to the animated fairy tale will start in the past and raise questions such as how Elsa got her powers. Australian Associated Press
